維摩經玄疏 2.37

2.37

Next, explaining the "contemplation of the Middle Way": "middle" takes non-duality as its meaning; "way" takes being able to penetrate as its name. Illuminating the one real truth, opening unhindered and without obstruction, is called the contemplation of the Middle Way. Hence the sūtra states: "The prior two contemplations are the path of expedient means; by relying on these two contemplations of emptiness, one can enter the Middle Way, dual-illuminating the two truths, mind after mind quiescing, naturally flowing into the ocean of sarvajñā."
